Description

Glass bead doped with 1 mol% Uranium4+ Ions – NEW!
Size about 10mm . Matrix: Ba-Li-Borate glass.

There is no measureable radiation coming from the beads so they are absolutely safe to handle.
the U4+ ions cause a slight green color under daylight and a strong green luminescence under UV light (395nm)

Beautiful optical glass beads doped with metal ions.

Elaborately and individually manufactured by us in the laboratory from highly pure reagents.
Gorgeous beads showing the typical colors of different metal ions in different oxidation states.

They can be used for save demonstration of different colors of the metal compounds or just for collecting.
